merge(3p/git): Merge git subtree at v2.29.2 r/1890

This also bumps the stable nixpkgs to 20.09 as of 2020-11-21, because
there is some breakage in the git build related to the netrc
credentials helper which someone has taken care of in nixpkgs.

The stable channel is not used for anything other than git, so this
should be fine.

+Instructions how to use this in Visual Studio:
+
+Open the worktree as a folder. Visual Studio 2019 and later will detect
+the CMake configuration automatically and set everything up for you,
+ready to build. You can then run the tests in `t/` via a regular Git Bash.
+
+Note: Visual Studio also has the option of opening `CMakeLists.txt`
+directly; Using this option, Visual Studio will not find the source code,
+though, therefore the `File>Open>Folder...` option is preferred.
+
+Instructions to run CMake manually:
+
+    mkdir -p contrib/buildsystems/out
+    cd contrib/buildsystems/out
+    cmake ../ -DCMAKE_BUILD_TYPE=Release
+
+This will build the git binaries in contrib/buildsystems/out
+directory (our top-level .gitignore file knows to ignore contents of
+this directory).
+
+Possible build configurations(-DCMAKE_BUILD_TYPE) with corresponding
+compiler flags
+Debug : -g
+Release: -O3
+RelWithDebInfo : -O2 -g
+MinSizeRel : -Os
+empty(default) :
+
+NOTE: -DCMAKE_BUILD_TYPE is optional. For multi-config generators like Visual Studio
+this option is ignored
+
+This process generates a Makefile(Linux/*BSD/MacOS) , Visual Studio solution(Windows) by default.
+Run `make` to build Git on Linux/*BSD/MacOS.
+Open git.sln on Windows and build Git.
+
+NOTE: By default CMake uses Makefile as the build tool on Linux and Visual Studio in Windows,
+to use another tool say `ninja` add this to the command line when configuring.
